atoms of matter must derive from these five fundamental solids -
that atoms are indestructible, and have always been and always will be in motion -
He held that matter was fundamentally constructed out of atoms. -
They were trying to turn lead into gold. It took many centuries for this concept of the chemical elements to evolve. -
He discovered the volume of a gas decreases with increasing pressure and vice versa. -
the total mass of products and reactants in a chemical reactions is always the same. This led to the theory of the law of conservation of mass. -
He thought atoms were the smallest particles of matter, he envisioned them as solid, hard spheres, like billiard -
Russian chemist who devised the periodic table of the elements -
process where by the energy from electromagnetic radiation, such as visible light, gamma radiation or other, hits an atomic electron whereby the energy of the radiation is transferred in its entirety to the electron causing the electron to be ejected from the atom. -
credited with the discovery of the electron, and he also came up with a thing call the "Plum Pudding" Model -
the energy of light is proportional to the frequency -
He is best known for his equation E = mc2, which states that energy and mass -
They were the chemist who conducted pioneering research on radioactivity. -
precisely determining the magnitude of the electron's charge -
The discovered that the atom is mostly empty space -
He discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element. -
English physicist who experimentally demonstrated that the major properties of an element are determined by the atomic number -
to find the allowed energy levels of quantum mechanical systems -
states that a particle's position and momentum cannot both be known exactly known. -
bombarded beryllium atoms with alpha particles. An unknown radiation was made
